'Glee' actress Jane Lynch discovered she was deaf in one of her ears when she was 7 years old. And that's apparently why she talks out of one side of her mouth. This is how she found out:
"My brother was switching ears with his transistor radio and I said, 'You can't do that. You can only hear out of one ear.' And he was like, 'No. I hear out of both!' I said, 'Mom, I only hear out of one ear!' And we went to the doctor. It's nerve deafness, probably from a very high fever when I was a baby."
